PROBLEM TO BE SOLVED: To simultaneously attain improvement in image quality of a dark part and highly-accurate camera shake correction. SOLUTION: A plurality of pieces of divided color pixel data 501 which is read by division exposure from an image pickup device within exposure time and consists of specific color components are corrected by blind deconvolution, pieces of divided color pixel data 501a after correction are positioned and added together. PSFs estimated for every piece of divided color pixel data 501a in correction are integrated based on a motion vector used for positioning of the plurality of pieces of divided color pixel data 501a to create PSFs of the whole frame. Pieces of non-divided color pixel data 502 and 503 which consist of color components except the specific color components read by batch exposure from the image pickup device within the exposure time are individually corrected by deconvolution using the PSFs of the whole frame. Pieces of pixel data 504 from which subject shake is reduced with high accuracy are obtained by coupling divided color pixel data 501b after addition to pieces of non-divided color pixel data 502a and 503a after the correction.
